Application filed July 2, 1912. Serial No. 707,227.

T all whom it may concern Be it known that 1, JAMES C. Gonoon, a citizen of the United Statesof America, residin at Detroit, in the county of Wayne and tate of Michigan, have invented cerd useful Improvements in Dough-Mixing Machines, of'which the following is a specification, referencebemg had therein to the accompanying drawmgs.

The invention relates to dough mixing machines and has for its object the obtalning of a construction in which the dough is mani ulated in a novel manner, being subjecte ,to a rolling as distinguished from a tearin or shredding action.

In t e drawings: Figure 1 is a side eleva tion of the machine; and Fig. 2 is a vertical section therethrough.

A is a substantially cylindrical receptacle,

forming the mixing chamber, and which at its bottom is provided with .a flattened portion B.

C is a hinged section forming a removable cover to the cylinder, but havin its nner surface forming a continuation of the inner surface of the body portion of the cylinder.

The cover is also provided with an opening D which is closed by a slide E, forming an observation 0 ening and also a means for introducin into the cy 'nder.

F is a rotatable shaft passing axially through the cylinder, .and upon which are mounted radial arms G arranged at oppos te ends of the c linder.

H are re s journaled at their opposite G so as to independently revolve. These rolfs are so positioned that in traveling through their orbit they will pass in proximity to the center of the flattened portion B, but during the remaining portion of their movement will bespaced from thewalls of the cylinder A. The inner wall of the cylinder A,instead of being concentric with the axis of the shaft F, is slightly eccentric in the upper ortion thereof,'.constituting the cover C an a part of the body, to provide greater clearance between said surface and the orbit of the rolls.

J isa hollow casing surrounding the shaft F, into which a cooling medium may be introduced to control the temperature of the dough within the cylinder. The rotary shaft and drum are supported upon a suitable frame K.

t e ingredients of the dough,

With the construction as described rotary motion is imparted to the shaft F by a suitable drive mechanism such as the gearing L, driven from the electric motor M. This will cause the shaft and radial arms to revolve, which carry the rolls H through their orbit, just clearing the center of the flat bottom B but spaced from the sides and to of'the receptacle. "When the ingredients or forming the dough are introduced they will first be stirred by the revolving rolls until a plastic mass is formed, after which the action will be a rolling one. When the dough mass is upon the bottom of the receptacle it will be squeezed by the passing roll which in re' volving about its own axis distributes the dough and prevents a shredding or tea-ring action. The mass however does not remain upon the bottom 13 but is carried around by the propellingaction of the rolls andin so traveling. rolls in contactwith the surface of the cylinder until it again rests upon the flat bottom B.' There IS very little interruption in the continuity. of the surface with the exception of the opening D, which is of such relatively small area as to not materially affect the result. When the manipulation. of the dough is completed the cylin-. der may be revolved upon its trunnions by a suitable mechanism such as the hand-wheel N, worm-gearing O, shaft P and pinions Q, engaging segmental rolls R on the drum so as to bring the cover 0 at the side. This cover is then opened and the dough mass ejected by the rotation of the shaft F and rolls H .carried thereby.

The machine in o eration will mix dough in a shorter perio of time with the expenditure of less'power, and will produce a better ploye do not fully understand the action, the results obtained I attribute to the substantial continuity of the inner surface of the receptacle-the flattened bottom portion thereof-- and the rolls, which are independently rev- Patented Apr. 6, 1915; K

3. A dough manipulating machine comprising a cylindrical receptacle having a and a revoluble member orbit in proximity to said flattened bottom but spaced from the remaining portions of the surface of said cylinder.

4. A dough manipulating machine comprising a cylindrical receptacle, a revoluble member eccentrically mounted within said receptacle, said member including a plu rality of radially extending arms all of which are the same length, rollers supported by said arms adjacent their terminals, saidrollers contacting with the mass to simul-' taneously compress the mass and convey the same across the surface of the receptacle.

5. A dough manipulating machine comprising a cylindrical receptacle havin a flattened bottom, a member revoluble within said receptacle, said members including rolls traveling in an orbit in proximity to the flattened bottom whereby there is greater clearance at the top of the receptacle than at the sides and bottom.

. 6. A machine for manipulating dough comprising a cylindrical receptacle having a flattened bottom and an upper portion slightly eccentric, a revoluble member within sai receptacle, and rolls carried by said revoluble member through an orbit in proximity to said flattened bottom, spaced from said sides, and having a slightly greater spacing from the top of said cylinder, there being a space at the advancing side of the roll permitting its free independent action on the mass.

7. A machine for manipulating dough comprising a cylindrical receptacle having a flattened bottom, a revoluble member eccentrically mounted within said receptacle, and rolls carried by said revoluble member through an orbit in proximity to said flattened 'bottom, the member being so mounted that the rolls are spaced to a greater extent from the top of the receptacle than from the bottom and sides.

A dough manipulating machine comprising a working surface to receive the dough, a plurality of rolls movable over said surface and spaced therefrom, said rolls being adapted to roll the mass of material continuously over said surface, one portion of said surface being offset inwardly with reference to the body thereof, whereby the rolls in their movement over the surface will be brought closer to the offset portion of the surface than with regard to the other portions thereof, and thereby exert greater pressure at'this point.
